As for this Syfy sequel to the torched-by-an-angel movie Legion, it's the kind of series that is best watched with the volume muted and your brain off. Silence will allow you to enjoy the sight of good and evil angels flying and fighting without actually having to hear any of the badly written and delivered dialogue that surrounds them. (Pity any actor who has to say lines like "There is no me without you.") And a thought-free approach will stop you from obsessing over why an American city would suddenly turn into Ancient Rome, or why the producers assume we've all seen Legion and we're all on board for the cumbersome back story. Because both are a mystery to me.

Rookie Blue | ABC, 9 ET/PT

ABC launches the third season of this Canadian import with a double-run that traps Andy and Dov in a diner hold-up while introducing Oliver Becker as a tough new inspector and Matthew Owen Murray as a new and immediately disliked rookie. Blue isn't exactly compelling television, but it's competent — which places it a step above its returning lead-in, Black Box, and its Syfy timeslot rival, Dominion.
